vertexone.net website review

67 files are served with short cache lifetimes, so returning visitors download them again (599 KiB).

About 647 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.5 s faster on a phone.

18 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.4 s.

Your mobile performance score is 44. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

8 third-party services load with your homepage (Google Tag Manager, Accessibe Accessibility Overlay and Hotjar and others), adding 1.0 MB and 1.3 s of main-thread time.

7 images could be 592 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 150 ms faster on a phone.

Google Tag Manager costs a phone 459 ms of main-thread work and 525 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

Accessibe Accessibility Overlay costs a phone 391 ms of main-thread work and 250 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

A phone's processor spends 3.1 s on main-thread work while loading, 1.7 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

14 long tasks block the main thread while loading, the longest for 237 ms. During a long task the page ignores taps.

About 10 KiB of CSS is downloaded but never applied on this page.

Polyfills for old browsers add 8 KiB JavaScript that modern phones do not need.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

Your largest element takes 20.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “EXPERIENCE IS EVERYTHING We connect water, gas, and electri…”.

The page becomes fully interactive after 23.5 s. Good is under 3.8 s.

Visually, the page fills in at 8.0 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 1.0 s in total while the page loads. Good is under 200 ms.

Real visitors wait 2.9 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 2.3 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.1 s for your server to start answering (75th percentile). Good is under 800 ms.

The first text or image appears after 1.9 s on a phone. Good is under 1.8 s.

5 images have no width and height attributes, so the layout jumps as each one loads.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 77 ms to 88 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.8 s to 1.9 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.0 MB in 106 requests on a phone: fonts 1.6 MB (3), scripts 1.3 MB (35) and images 926 KiB (31). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.12 g of CO₂e: 134.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 button has no accessible name, so screen readers announce just “button”.

Scrollable region must have keyboard access: 1 element on the page fails this check, rated serious by axe-core.

5 images have no alt text, which hurts accessibility and image search.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

8 visible links have no text or label, so screen readers cannot say where they go.

Headings skip levels (h2 → h4 and h4 → h6), which makes the page harder to scan with a screen reader.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

The homepage links to 109 pages on vertexone.net and 0 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

There is no https://www.vertexone.ai/llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

We fetched 15 pages linked from your homepage (of 41 found) and read each the way a search engine does.

2 errors were logged to the browser console while the page loaded, for example “Clearbit: Please migrate to the new script. See https://grow.clearbit.com/migrate”.

Large scripts ship without source maps.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

The homepage shows no opening hours. If customers visit or call, show when.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

The homepage carries about 704 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Hotjar and HubSpot and 1 more (measured from a US location before any click). A consent tool (HubSpot cookie banner) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 14 cookies (measured from a US location before any click).

Loading the homepage contacts 32 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
